ELECTRIC ATOMIZER HEATER.

Application filed April 25, 1923. Serial No. 634,495.

To all whom. it may concern:

Be it known that I, FREDERICK T. Krrorrnn, a citizen of the United States, residing in New Brunswick, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Electric Atomizer Heaters, of which the following is a specification.

This invention relates to atomizer-s and aims to provide certain improvements thereno. 1

The invention provides a device by means of which a hot or warm spray is produced and in which the liquid or air, or liquid and air, is heated after it leaves its container, and preferably in theimmediate vicinity of the nozzle where the liquid is entrained by the air jet. The invention further provides a device of the character described which is of simple construction, self-contained, portable, easily taken apart, and in which parts may be readily replaced by others.

Two embodiments of the invention are the accompanying drawing, in which- Figure 1 is a sectional view of one embodiment of the improved atomizer, and Fig. 2 is a similar view of another embodiment. 1

Referring to said drawings, numeral 10 designates the nozzle of the device through which air and liquid are adapted to issue, the liquid being entrained by the jet of air and atomized or divided according to the usual mode of operation of an atomizing device.

Liquid from any suitable or desired source, as a bottle, 12, is drawn to the nozzle 10 through a tubular orhollow part 14 connnunicating with said nozzle and air from any suitable or desired source, as from a hose connected to a compressed air reservoir (not shown) may be supplied to said nozzle 10 through atube 16 having an outlet or nozzle 18 suitably arrani d with reference to the nozzle 10 to entrain the liquid drawn to said nozzle. According to the embodiment illustrated in Fig. 1 thetube 16 is arranged inside and concentric of thetube 14, and the air nozzle 18 is 'u'st behind and in line with the nozzle 10. l Vln'le air has been described assuppliedto thetube 14 and liquid to thetube 16, this arrangement is not essential, as an inversearrangement is suitable. A

siphon tubev 20 attached to and communicating with theliquid tube 14, and adapted to project into thebottle 12, may be provided. Thetube 16 may fit fairly closely inside of thetube 14, as the surface irregularities will provide sufficient area for the flow of liquid to the small orifice in the nozzle 10. Thetube 14 is preferably detacha'bly connected to thetube 12, and to this end thetubes 12 and 14 may have a taper fit, as indicated at 23.

Suitable means 25 are provided for heating the liquid, or air, and preferably both, after the liquid, or air, or liquid and air, leaves its container and preferably in the immediate vicinity of the nozzle 10. Ac cording to the embodiment illustrated in Fig. 1, the heating means 25 is in the form of an electrical heating unit or,cartridge 27 of any suitable or desired construction.

adapted to fit inside of theair tube 16, and is preferably detachably secured to the device, as by means of a screw-plug 29 engaging threads on the end of saidtube 16. The plug 29 shown is of the usualswitch coupling type and the heating element in thecartridge 27 is connected to the coupling plug 29 by means of insulatedconductors 30, 31.

Air may be admitted to thetube 16 through aconduit 33 in communication therewith, theconduit 33 being connected to any suitable source of supply, as to an air tank through ahose connection 35, said hose being joined to said conduit in suitable manner, as by means of a taper-plug 37.

The fit between thecartridge 27 and the inside oftube 16 may be'tairly close, as the surface irregularities of the parts will be enough to admit of suficient air being delivered to the nozzle 18.

By removing thetubular part 14 andcartridge 27, the several parts of the device are thereby detached, and substantially all parts exposed for convenient inspection, cleaning and repair.

Ahandle 40 may be, provided for convenient manipulation of the device.

A second embodiment of the invention is illustrated in Fig. 2. 60 designates a liquid tube and 62 an air tube. Thenozzles 63, 64 of the tubes are brought together in such manner that the jet of air from thenozzle 64 entrains liquid from thenozzle 63 and thereby produces the atomization of the liquid.

The heating means is here illustrated as in the form of a sleeve having a central opening 66 through which thetubes 60, 62 are adapted to pass, and which sleeve contains an electrical heating element of any suitable character to which electricity is conducted throughwires 68, 69. The sleeve 65 is, preferably made detachable from thetubes 60, 62.

Operation: Electricity being admitted to theheating element 25, the said heating element becomes hot. In Fig. 1 this heating element being in the form of acartridge 27 inside of theair tube 16, beats the air flowing over it to the nozzle 10, and the heat radiated from the air in thetube 16 is imparted to the liquid in thetube 14 surrounding the saidtube 16. Both the liquid intube 14 and the air intube 16 are thereby heated, and theheating element 25 being in the vicinity of the nozzle 10, only very little heat will be lost by either the air or liquid by radiation between the heating element and the nozzle. The spray which issues from the nozzle 10 will therefore be in fact a heated spray despite the cooling due to expansion of the air after leaving the nozzle 10. In Fig. 2 theheating element 25 being in the form of a sleeve 65, heats by inward radiation both theliquid tube 60 and theair tube 62, and the liquid and air re main heated while passing to thenozzles 63, 64, and a spray which is in fact heated is readily obtained.

The invention may receive other embodiments than those herein specifically illustrated and described.

What is claimed is:

1. An atomizin device having a nozzle, means for supplylng liquid and air to said nozzle, and means for heating fluid supplied to said nozzle between its source of supply and said nozzle.

2. An atomizing device having a nozzle, means for supplying liquid and air to said nozzle, and electrical means for heating fluid supplied to said nozzle between its source of supply and said nozzle.

3. An atomizing device having a nozzle, liquid and air tubes leading thereto, and heating means adj acent said nozzle for heating said tubes.

4. An atomizing device comprising a nozzle, a tube for conducting fluid to said noz- 211;), and a heating element located in said tu e.

5. An atomizing device comprising a nozzle, concentric tubes leading to said nozzle,

and a heating element located in the inner concentric tube.

6. An atomizing device comprising a nozzle, concentric tubes leading to said nozzle, and a heating element located in the inner concentric tube, said heating element being in the form of a cartridge substantially conforming to the inner contour of the tube in which it fits.

In witness whereof, I have hereunto signed my name.

FREDERICK T. KITCHEN.
